INVENTOR ATTORNEY United States Patent SMOKING PIPE TOBACCO CARTRIDGE PACKAGES William Trow, New York, N. Y., assignor to Pipe-Pac Tobacco Corp., New York, N. Y., a corporation of New York Application September 3, 1952, Serial No. 307,648

2 Claims. (Cl. 206-485) This invention relates to smoking pipe tobacco cartridge packages.

An object of this invention is to provide a package of the character described, comprising a smoking pipe tobac co cartridge in the form of a sleeve-like container of woven fiber glass having the ends gathered or twisted and closed by a staple, said cartridge being enclosed in a tube of thermoplastic, light transmitting sheet material, having the ends thereof flattened and heat sealed, with the outer twisted or gathered ends of the cartridge sleeve caught between the flattened heat sealed ends of the tube during the heat sealing operation, to center the cartridge with respect to the tube. Such a cartridge is moisture proof to keep the aroma of the tobacco fresh and to keep moisture from coming out. Furthermore, the cartridge or plug of tobacco is centered so that it cannot move around within the plastic tube. Furthermore, with such construction, the gathered ends of the fiber glass sleeve are prevented from unravelling.

A further object of this invention is to provide a compact and durable package of the character described, which shall be relatively inexpensive to manufacture, easy to use and yet practical and eificient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the construction hereinafter described, and of which the scope of invention will be indicated in the following claims:

In the accompanying drawing in which is shown various illustrative embodiments of this invention:

Fig. 1 is a top plan view of a smoking pipe tobacco cartridge package embodying the invention;

Fig. 2 is a cross sectional view taken on the line 22 of Fig. l; and

Fig. 3 is a cross sectional view taken on the line 3-3 of Fig. 1.

Referring now in detail to the drawing, designates the package embodying the invention. The same comprises an inner smoking pipe tobacco cartridge or plug 11 packaged or enclosed within the outer tube 12. The cartridge or plug 11 comprises a tubular sleeve 13 of woven fiber glass strands, within which is a mass 14 of smoking pipe tobacco. The ends of the sleeve 13 are twisted or gathered as at 15 and these ends may be held in gathered position by staples or pieces of wire 16.

The outer covering, casing or tube 12 is preferably made of thermoplastic, transparent or light transmitting sheeting. The tube 12 may be made of a single sheet having overlapping longitudinal portions 17 either adhered together by glue or heat sealed by application of heat or high frequency current. The ends of the tube 12 are flattened and the end portions are heat sealed or otherwise attached as at 19. The outer ends 15 of the cartridge are caught centrally between the heat sealed flattened portion 19 so that the cartridge as a whole is centered with respect to the tube 12. Instead of heat sealing, any adhesive may be used. The sheet material of which the tube 12 is made is moisture proof so that the package as a whole is moisture proof to keep the tobacco aroma and to keep the tobacco fresh. The tube 12 prevents moisture from coming out. Furthermore, the cartridge or plug is centered so that it will not shake or move around within the outer package. The twisted or gathered ends 15 are prevented from unravelling because they are adhered between the flattened attached together ends 19 of the outer tube 12.

The purchaser of the packages 10 can easily break open the outer tube 12. The cartridge 11 may then be inserted into the smoking pipe and the tobacco 14 smoked. After the tobacco is fully smoked, the cartridge is removed. The fiber glass strands will not burn as they are resistant to the heat created during the smoking of the tobacco. The ashes will remain within the cartridge sleeve 13, and are hence easily removed from the bowl of the pipe.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A smoking pipe tobacco cartridge package comprising a sleeve of woven heat resisting material, tobacco within said sleeve, the ends of the sleeve being twisted, means to grip the twisted ends of the sleeve, and an outer tube of thermo plastic, light transmitting, sheet material surrounding said sleeve, with the twisted ends of the sleeve positioned centrally axially of the tube between the flattened ends of the tube the ends of the tube being flattened and adhered together over the twisted ends of the sleeve positioned therein.

2. A smoking pipe tobacco cartridge package comprising a sleeve of woven fiber glass strand-s having each of the ends thereof twisted, smoking pipe tobacco within said sleeve, and an outer wrapper comprising a tube of synthetic plastic sheeting, the end of each tube being flattened and adhered together over the twisted ends of the sleeve disposed centrally between the adhered together flattened portions of said tube.
